The 23-year-old has been linked with the Premier League and his agent has suggested that a move away from the Bundesliga club could happen
Hakan Calhanoglu could leave Bayer Leverkusen this year if a suitable transfer bid is made, according to the midfielder's agent.
The 23-year-old is unable to play for the remainder of this season as a result of a FIFA ban that was upheld by the Court of Arbitration for Sport last month.
It was ruled that Calhanoglu had reneged on an agreement to sign for Trabzonspor from Karlsruhe in 2011, with FIFA opting to suspend him from football for four months.
